Patented May 8, 1945 UNITED; STATES; PATENT OFFICE COLTER; I c ArthurLaitinen, Kimball, Minn. Application May 6, 1944, Serial No. 534,433 7 2Claims (01. 97-209) This invention relates to a colter device, I

An object of the invention is the construction of a simple and veryefficient colter device which will prevent the plow from lifting out ofthe ground by eliminating the gathering of cornstalks or weeds of anykind in frontof the colter device. r g

Another object of the invention is the construction of a very efficientand novel frame, mounted in a novel and efficient manner upon thestandard of the device, which standard is adapted to be attached'to thecommon plow beam of aplow.

A still further object of the invention is the construction of a noveland efiicient colter device in which the frame will. efliciently slideor pass over, as a runner, foreign'matter, such as stalks and the like,and which frame will also have a slight pivotal or turning movement uponits supporting standard, whereby the life of the device is increasedbyeliminating the possibility of the frame being broken off the standard.

With the foregoing and other objects in view, my invention comprisescertain novel construc-' tions, combinations, and arrangements of ,partsas will be hereinafter fully described, illustrated in the accompanyingdrawing, and more particu larly pointed out in the appended claims.

Referring to the drawing in which the pre- Figure 7 is an enlargedfragmentary perspective 7 I l designates an ordinary plow beam and 2 amold ferred embodimentof this invention is illustrated,

board. The colter device comprises a substantially V shaped frame 3 uponthe inner or lower end of which is pivotally mounted colter wheel 4; TheV-shaped frame is curved upwardly at its outer end and its sides 5 areconnected at their bottom edges by a runner bottom 6, Fig. 4. Thisbottom permits the frame to slide over corn stubble and weeds and thelike, and should any dirt'ha'ppen to fall between the sides 5 and ontothe, runner bottom 6, "the same will readily pass out of the opening Iand onto the ground.

The standard 8 extends through two parallel webserrigw that are integralwith the sides 5 of the V-shaped frame. These webs9 haveregistering'apertures l0 through which the lower end of the standard 8extends. A horizontal slot II registers/with the space between webs 9and in this space is placed collar 12; collar [2 fits around thestandard 8 as clearly seen in Figures 5 and 6. The collar I2 is providedwith an enlargement l3 and into this enlargement extends a set screw I4which is adapted to impinge tightly against the standard 8 (Fig. 6),thereby locking the frame 3 in an adjusted position upon-the standard.

The slot ll permits the frame 3 and wheelv 4 to have a slight horizontalmovement upon the standard, as indicated by the arrows A, Fig.2,

whereby the life of the device is increased be-] cause of this yieldingaction in case the wheel strikes a large rock or considerable stubble,that might otherwise injure the device ifit were not i for the novelconstruction and movement, as just described- A cotter pin I5 is placedin the lower end of the. standard 8, and on the standard just abovecotter pin l5 i a washer It. This structure keeps the standard 8 frombeing accidentally pulled out.

of the webs 9 and collar 1 2, but does not interfere with the operatorsready adjustment of the frame and its wheel to the desired position.

' The standard 8 is mounted on beam I by passing the standardthrough-two loop bolts l1 (Figs.

8 and 9), with one of these loop bolts placed above and onebelowthe plowbeam I, Suitable sleeves H! are placed on these loop bolts in engagementwith theplow beam I, and on the sides of the plow beam l are strap ironsI9 through which the loop bolts extend. Suitable nuts .20 are on theouter ends of the loop bolts I1 in engagement with the outer strap ironl9, whereby the standard 8 is securely attached to the plow beam l. Ofcourse, it will be understood that the standard8 fits tightly into theloops of bolts ll,

The frame 3 is formed r I I is tosay, the upper or outer .half curvesupward m r "sly whereas the .inner or lower half .curve downsufficientlyto prevent'any sliding movement-oi? the standard upon'beam I when in afixed assems bledposition thereon. C a From the vforegoing descriptionitis to be un derstood that I have provided a standard upon which isadjustablymounted a wheel-carrying frame, the adjustment being novel asWell as the frame,iwhereby a highly eflicient device is producedthatwill bea big help during plowing time, because it, will slip over solidobjects like What I claim is:

A colter,'compr1sing a V-shaped wheel-car rying'frame, including twoupstanding sides; said sides-at outer'ends having a runner bottominvtegral withonly their lower portions, said runner bottom having-itsinner end near the middle of said frame, a pair oi -transverseparallel'webs en- 1 tirelybetweenthe top andtbottom edges of saidupstanding sides and .integral therewith, the

rocks, stumps, etc.,-in stead of breaking off the counters'hank.

It is to be understood that this colter-'device'-- can be vfastened toanyordinary plow .and, sfure lower web .of' said pair having one of itsside a edges contiguous to v therinnerend or :said runner bottom,whereby an opening is formed between -said lower web and the inner endof said runner i "bottom, one of said upstanding sides, being pro- 4.5;
